Each way payout wrong?

so i threw a cheeky each way bet on some nags yesterday, expecting the usual payout math. except the place return was off by a chunk, and i checked the fractions - no funny business there. nothing weird with the terms listed, all above board as far as i could see. started thinking maybe there’s a new rule or sneaky update to the paytable i missed, or maybe the dead heat rules? but i don’t see anything in the race result to explain it.

i screenshot everything, because after that time they tried to slip a void bet past me during a tennis match, i don't trust their little "settlement" button anymore. have you all had this kind of mismatch lately? wondering if it's a glitch or they're just counting on us not double checking. my mate says to let it go but c’mon, it’s the principle.
